Where is a gas fuse in a Kenmore oven?


Gas ovens don't have a fuse. Won't the oven light?

Pilot Light won't stay lit?

We get asked this question many times.

If you light your pilot light, hold in the button and then when you release it and the pilot light goes out, generally you need a new thermocouple. Gas repairs can only be undertaken by a qualified gas technician so you can't do this job yourself.

The thermocouple is a safety device that recognises that the pilot has a good flame and is enough to ignite the main burners. The thermocouple open that valve to the burner.

In limited circumstances the thermocouple doesn't need replacing, either the shield that aims the flame to the thermocouple has become dislodged, or the pilot jet is a little blocked by debris. Either way, having the appliance serviced by a qualified gas fitter is the way to go. I am sure you will have seen news stories about explosions caused by gas leaks and faulty appliances.

Oven pilot will not stay lit


Strange to hear about a pilot-flame. Is it an old oven? Commercial unit? Look for a small valve at the end of the pilot gas-line and see if it is shut off. If it's on, okay. But, is gas getting there being blocked elsewhere? There may be a flame safety-switch, a sensor by the pilot, or some other thing that has a release button for lighting the pilot. You hold it in until the sensor heats up, and then it will stay lit. After that, there may be a re-set button to get gas to the main burner element. Basically, you have to trace lines back until you find the hindrance. CAUTION:With all gas appliances, you have severe danger of causing an explosion, and untimely death, or injury, so if you have any doubts, get a qualified guy on it! (It takes a while to grow a beard back, too.)

I have a garland oven model st286 it wont light even though there is gas getting to it and the spark is working. It lights if you light it manually


Instructions
  1. Access the burners inside your oven by removing the access panel in the front of the oven or by opening the broiling drawer, depending on your particular model.
  2. Determine if the pilot itself is lit, since some ovens have a small flame on the pilot at all times that then grows and extends to the burner when the oven is turned on. The lack of a pilot flame indicates the oven thermostat is malfunctioning or there is a problem with the gas hose. Check the pilot itself to see if it is clogged with debris or grease that could be preventing the flame from staying lit.
  3. Determine if the pilot flame will grow if it is lit by turning on the thermostat. If the pilot flame doesn't extend, the thermostat itself likely needs replacement. If the flame is extending but the gas valve is not opening, the safety valve could be dirty or defective. The flame should be blue in color. A yellow flame indicates the pilot is dirty and is not burning hot enough to get the main burner to ignite.
  4. Light the burner on the top of the oven with a match if the igniter doesn't appear to be effective. If it lights manually but will not light automatically, the igniter is likely faulty. Do not do this if there is a heavy smell of gas in the kitchen, since there could be a risk of a fire. In that circumstance, turn the oven off, ventilate the room and call a technician.
  5. Listen for any sounds of gas hissing or a clicking sound indicating the oven is trying to turn on. If there is no response from the oven at all, the gas may not be functioning properly and will need to be examined by a technician for safety purposes

Pilot light is lit both on oven and stove top... previous user says to turn on gas and lite "sensor" or "2nd pilot" it stays lit as long as oven knob is on but oven burner does not light. "sensor" goes out...


On standing pilot ovens the maker uses a safety device to kill the gas in case the pilot blows out. As long as the pilot is lit the gas safety magnet hold the gas flap open inside the safety valve.To save energy the pilot has 2 flames. The standby pilot keeps the cooper/nickel probe/sensor warm so the oven will light faster, the 2nd pilot is much larger, only appears when the oven control is turned on and this is what opens that valve. So when you turn the oven knob on the gas leaves the control and goes downtown to burner land. If that pilot is lit and that slow opening flap inside that valve is open, then the gas will enter the burner tube and ignite when it hits the pilot. Pretty slick ain't it? So what can go wrong? With age the flap inside the safety valve will wear out, get weak, work a little, then take forever to light and eventually just goes bye bye. When you get ready to replace the valve it ain't gonna be adjusted exactamundo, you gotta tweak it. To do so after bubble testing for leaks and lighting the pilot you turn it on and observe the flames. It needs to be not more than half way up the flame spreader. If it is to small of a flame it will take forever to bake even a pie shell, if it is too much their could be burned bottom and in some cases fire hazards. OOPs.

Oven lights on low flame but will not come up on high flame .cannon chester cooker.suspect by pass is not working. Do I need control knob/thermostat with the phial. Thanking you.


all gas range ovens have a small metal box in the back upper area of the broiler burner; a gas line runs into this box as do two wires; this is a "flame control " gas valve; the way it works is: after the pilot has been lit as you turn the oven temp control a heating element in the box causes a small valve to open allowing a larger amount of gas into the oven burner to ignite the whole burner If you can only get pilot flame on high replace this valve

Spark module clicks and gas will not stay lit, flame comes on but goes out


hi Clogged burners are a very common problem with gas ranges because foods spilled on the burners block the gas ports and prevent ignition. On some gas ranges you can remove the top ring of the burner to expose the ports. Here's how to clean a burner:
Step 1: Turn off the power supply, both gas and electric, to the range. Then remove the burner.
Step 2: Soak the burner in a solution of mild household detergent and water. Clean it with a soft cloth.
Step 3: Clear the gas ports with a pin or needle, rinse the burner, and let it dry. Caution: Do not use a toothpick or matchstick to clean the gas ports. If the tip of the wood gets stuck in the burner ports, it could cause a serious blockage.
Step 4: When the burner is completely dry, replace it, and turn on the power and the gas supply.
thank u.................

Vulcan oven will not stay lit


I would take out the pilot and clean it up and see what happens,also look behind the unit and see if theres a gas regulator on the gas line,if so you will see a nut on it take it off with a pair of pliers and clean as well.that valve is actually the saftey valve,when the pilot lights the flame impinges on the thermocouple and that sends a millivolt back to that valve in order to open.if none of these resolve your problem i would replace the thermocouple first as this is a cheap part and easy to put on.if you need a part # i can give it to you.let me know.
